Dear cluster users,

due to the large interest in the last Julia workshop there will be a second identical one. You can find registration and other details below.

Best regards
Your HPC Team


We would like to invite you to the Julia Workshop, 22-24 of June 2021, organized by the competence network HPC.NRW and Paderborn Center for Parallel Computing (PC²). 
Julia is a new and exciting language for scientific computing, data analysis and many other purposes.

The Julia Workshop is suitable for beginners and intermediates. The only prerequisites are a strong interest to dive into Julia and basic knowledge in any programming language. 
The event includes Hands-on and Q&A sessions. Details about the topics covered and the registration can be found at: 

https://events.uni-paderborn.de/e/julia2021S

The number of seats is limited and the allocation of seats is done by the HPC.NRW member universities. The course is free of cost for members of German universities or publicly-funded research institutions in Germany. 

We would be happy if you could forward this announcement to potentially interested students or colleagues. 

Best Wishes 
The competence network for high-performance computing in NRW: HPC.NRW

Dear cluster users,

we have partnered with renowned C++ programming trainer Klaus Iglberger to bring you a 4-day online intermediate-level C++ course for free. The course will take place in the week from June 15 to 18 and will be held in English. It is the followup course to the beginners’ course Mr. Iglberger gave last year. 

You can register and find more details on the course topics here: https://events.uni-paderborn.de/e/cppintermediate

Note that this course requires some C++ experience, either from the previous course or equivalent (you can find the previous course’s topics here).

Mr. Iglberger has many years of experience both in scientific programming and in giving courses like this one to academic and industry customers. We are lucky to get this chance as his schedule is normally booked years in advance.

We only have two conditions:

  1. Please give detailed feedback. We are using this course as a test for future courses run in cooperation with other universities in NRW. You will be asked to fill out a feedback form at the end of the course.
  2. Out of fairness to your colleagues please only register if you are certain that you will attend. If you have to cancel before the course, please tell us. This will give people on the waiting list a chance to attend.

The course will be held online via Zoom. Meeting details will be emailed to all participants shortly before the first day of the course.

Best regards
Your HPC Team

Dear cluster users,

we have identified the most likely cause for the problems with crashes of computations with Abaqus, LS-Dyna and ORCA and have fixed the problem. If you use one of the mentioned programs, please check whether your computations run without problems now on OMNI. We would also like to remind you in this context that the HoRUS cluster will be shut down very soon.

Best regards

Dear cluster users,

the MATLAB course that was scheduled for tomorrow has been moved to a new date:

Thursday, May 20, 9:00-12:30
Friday, May 21, 9:00-12:30

This means the course has been divided over two half-days instead of one full day. The content will stay the same however. There are also enough free spaces open. If you wish to register despite the course being in German, you can find more details (in German) here. Otherwise, the course will be held in English next semester as usual.

Best regards

Dear cluster users,

on next Wednesday, April 28, from 12:00 until about 16:00, due to necessary maintenance work, there will be a brief disruption of the OMNI cluster. This concerns especially the file systems /work and /fast which house the workspaces. 

Your jobs will not necessarily abort. However, jobs that are running at the time of the maintenance may abort or run incorrectly. We will set up the queues such that as few jobs as possible are running at that point.

Please check whether your jobs completed correctly after the maintenance point.

Best regards
Your HPC Team

Original message (12:00):

Dear cluster users,

currently access to OMNI login nodes is not possible. ZIMT is already working on a solution. We will let you know when the problem has been fixed.
